1. Requirement of auxiliary gas for 10kw-class cutting machine
| Gas type | Oxygen (O2) | Nitrogen (N2) | Air |
| Main cutting material | Thick carbon steel, medium and thin copper | Stainless steel, aluminum, brass, medium and thin carbon steel, galvanized sheet steel | Stainless steel, aluminum, brass, medium and thin carbon steel, galvanized sheet steel |
| Require | 1. Purity: >99.99% | 1. Purity: 99.999%2. Pressure: 1.6-3.0MPa3. Vaporizer: ≥100 square meters | 1. Pressure: 1.6-3.0MPa2. Dewatering and degreasing treatment of compressed air3. Drain regularly and replace the filter kit |
| Cutting effect | 1. The cutting section is black | 1. The cut section is silvery white | 1. The cutting section is gray and black |
| recommend | Use liquid oxygen to ensure stable air pressure and long use time | Due to the large amount of nitrogen, it is recommended to use a storage tank, which is filled at one time, has a long continuous use time, good pressure stability, and relatively low cost. | It is recommended to use a high-power compressor to ensure continuous and stable air pressure |
| problem | 1. When the oxygen purity is not enough, the cutting and oxidation are insufficient, and there will be slagging or continuous cutting problems. | 1. When the nitrogen purity is not enough, the cutting surface will turn yellow2. When the nitrogen pressure is insufficient, the cutting surface is stratified or cut continuously | 1. When the air filtration is not sufficient, the pipe of the cutting machine and the lens of the cutting head will be contaminated, and the loss will be serious2. When the air pressure is insufficient, the cutting surface is stratified or cut continuously |
In addition to the requirements for auxiliary gas at the source, the entire pipeline such as the diameter of the gas pipeline and the diameter of the valve inside the cutting machine must be thickened to ensure sufficient air flow and prevent the source pressure from being enough to reach The pressure drop of the cutting head is serious, resulting in insufficient air pressure.
2. Other peripheral configuration requirements
1.Water cooling machine requirements
Recommendation: The 10kw-class laser has a large amount of heat and has high requirements for refrigeration. You should choose a big brand manufacturer, such as Fei, Dongluyang, Hanli, etc.
Requirements: Optional chillers for 10kw-class cutting machines. Cutting machine manufacturers should pay attention to the cooling capacity, water flow, and water pressure of the water cooling machine (MAX 15KW laser cooling requirements: cooling capacity 35KW, water flow 160L/min, Water pressure≥4.5bar)
2. Environmental requirements for 10kw-class lasers
Requirements: The 10kw-class laser has high requirements for external temperature and humidity. In order to ensure the stable processing of the cutting machine, an air-conditioned room must be installed separately for the 10kw-class laser, which is isolated from the outside world. It can prevent condensation in summer and icing in winter, keeping the laser in the best working environment and prolonging its service life
3. Cutting machine requirements
Requirements: The 10kw-class cutting machine needs to cut thicker and larger plates, so the bed should be designed to be thicker and stronger. In addition, during the cutting process of a 10kw-class laser, the internal temperature of the cutting machine will be higher, the bottom needs to be covered with insulation materials (insulation tiles, insulation bricks), the rack requirements are thicker, and the exhaust dust removal system is more robust and smarter.
4. Sports motor requirements
Requirements: 10kw-class cutting machine, with larger format and faster cutting speed, so the motion motor is required to have faster acceleration, more accurate accuracy and greater load-bearing capacity
